title: Swift heavy ions for controlled modification of soft magnetic properties of Fe₀.₈₅N₀.₁₅ thin film.
abstract: It is shown that the soft magnetic properties of amorphous Fe₀.₈₅N₀.₁₅ film can be modified in a controlled manner by irradiation with 120 MeV Ag ions. Irradiation causes relaxation of short range as well as long range stresses, resulting in an improvement in the soft magnetic properties. Nuclear resonance reflectivity has been used to measure the diffusion length of Fe atoms as a function of irradiation fluence. It is found that the atomic motion associated with irradiation is not expected to modify significantly the interfaces with substrate or other layers.
